DART-MX8M-MINI E-Con Camera

Introduction

The following instructions will help you to integrate E-Con MIPI camera support into Variscite Yocto images for i.MX8M and i.MX8MM platforms.
This will allow you to stream images/video from a E-con camera(s) connected to Variscite evaluation platforms.

Download Variscite Yocto BSP

Please follow Build Yocto from source code.
Execute steps 1-4.3 to download the BSP sources, but don't start bitbake yet.

Download and install E-con meta layers

$ wget ftp://customerv:Variscite1@ftp.variscite.com/E-Con/econ-4.14.98.tar.gz
$ tar xf econ-4.14.98.tar.gz
$ mv econ-4.14.98/meta-econ-imx8 ../sources

Download and install Variscite kernel patches

$ wget ftp://customerv:Variscite1@ftp.variscite.com/E-Con/sumo-fsl-4.14.98/recipes-kernel/linux.tar.gz
$ rm -rf ../sources/meta-variscite-imx/recipes-kernel/linux
$ tar xf linux.tar.gz -C ../sources/meta-variscite-imx/recipes-kernel

Customize configuration files

Customize bblayers.conf

Add the following lines to conf/bblayers.conf

BBLAYERS += " ${BSPDIR}/sources/meta-econ-imx8 "

Customize local.conf

Add the following to conf/local.conf under your Yocto build directory:

Add E-con driver:

MACHINE_ESSENTIAL_EXTRA_RDEPENDS += "kernel-module-econ-camera-driver"

Add E-Con DTB files:

KERNEL_DEVICETREE_append_imx8mm-var-dart = " \
        freescale/fsl-imx8mm-var-dart-econ-camera.dtb \
        freescale/fsl-imx8mm-var-som-econ-camera.dtb \
        freescale/fsl-imx8mm-var-som-econ-camera-rev10.dtb \
"

Build Yocto image

Continue following Build Yocto from source code from where you left off, to bitbake and install an image.
